Wow, looks like I've dived into a hot topic here!! I too will have it work it out on paper and trial it in 2014. We've 2 small children who will love it so it will be worth it for them if nothing else. My father used to have a few and really enjoyed it, I know I will.
Turning to profitability, I can't see the price of pork changing much until consumers change their buying habits. At the moment they will buy as cheap as they can and the supermarkets will strive to meet that demand, turning the screw on producers to comply. The celebrity chefs have done a lot to educate the public but household budgets are tight. Most people want cheap convenience and good produce sadly doesn't fit into that category.
Putting that to one side, what breed creates the best bacon and how well is taste defined by the type of feed?? That question should stir a few comments over Christmas!!!!
